Sewage in a tub or shower, toilets that gurgle when the sink drains, or water at a floor drain means the main is blocked. Stop running water and avoid flushing. We clear it from the cleanout and can run a camera to check for roots or a broken pipe.

What you can do before we arrive
Stop running water and do not flush. If you can find the outdoor cleanout, loosening its cap slowly (stand back) can let the backed-up water drain outside instead of into the house.
What we see in Upstate homes
Tree roots are the most common cause of main line clogs we see around Greenville, especially on lots with mature oaks and willow oaks near clay sewer laterals. In homes on septic, which are common past the city limits and around Belton, a main line backup can also mean the tank or the outlet baffle needs attention.
Keeping it from coming back
Keep wipes, paper towels and grease out of the drains, and if roots have been cut from your line before, schedule clearing every year or two until the damaged section is repaired.
Questions about main sewer line clog
Is a main line clog my responsibility or the city's?
The lateral from your house to the public main is usually the owner's. If the backup is in the public sewer, the utility handles it. A camera helps show where the problem is.
Why does my tub fill when I flush the toilet?
The tub drain is the lowest opening on the system, so when the main is blocked, wastewater backs up there first.
Can roots be removed for good?
Cutting clears them, but they grow back through cracked joints. A lining or replacement of that section is the lasting fix.
